Similar; characters 'of reierence'a're ein ployed in' all "ofthe' above dscribed views, to indic tecor espondingpart A Rejerring now, more particularly, to the accompanying drawings, there is rovided a man; supporting T frain'e generally indicated by tl'le'nuineraljl pf a substantially rectan nla'r" configuration preferably comprising side pieces 2 embodying-upper bars and lower ba'r'sfd' the end pbi tions "or which latter; are ofi-set upwardly and; arranged" in close "relation with the end portions of the upper" 3 while'jour'naled through the loopedterininal's'ii oftlie tease and rare the ver'tical shanksfi of caster aided? the lower ends 8' of which serve to rotatably support caster wheels 9. The shanks 6 are formed with collars 10 for supporting the lower bar'sfl' while set-screws 11 areniounted through the looped terminals of the upper bars and frictionally" engaged with the shanks "6 'to; :clainp the shanks, of either the frontqpr the rear wheels rigidwithI respect tdthesidepieces'Q. Handlebars 12 are connected to the 'opposed front axles and also to the opposed rear aides and serve as ainea'iisfor shifting or steering thedevice, asisapparent. The upper bars 3 and the lower 'bars'yt are connected b nongatea closs-barsls and 14, while the upper crossbaisjflii are braced with respect to the'lower cicss-barsqliby'means of tie rods15 and vertical bare-16, thetie rods'bein'g arranged at'aii incline-"asindicated. The upper and lower bars" -3 and 4' are rigidly connected to the end of the vertical bars '16 by means of braces 17. Longitudinally disposedbracing bars 18: are arranged between the upper bar '13 'la'ndthe' lower bars l lito increase the-rigidity of the'framef :The narrowrops? comprises a body 19 from which depend teeth 20. Hooks 21 extend from the forward ends of the harrow body 1 9 at suitable intervals from the ends thereof and engage with connecting elements generally indicated by the numeral 22 carried at suitably spaced intervals on the draw bar 23. These connecting elements 22 consist of a horizontally disposed loop 24 and a right angularly extending shank 25 which terminates at its upper terminal in a hook 26. Fasteners 27 are employed for securing the connecting elements near the point of juncture of thehook with the chains 30 and 31 are employed. 'Outer termin'als of the chains 30 are anchored to the outer longitudinallydisposed lower bars 18 and extended downwardly and trained about pulleys 32 on the harrow body 19,-the chain being thence extended upwardly and trained about the pulley wheel 33 on-the before mentioned longitudinally disposed bar and thence extended transversely of the devicebeing finally trained about one of the drums 34: in the locking and retaining body 35.

The chain 31 is connected to one of the] medial and lower longitudinally disposed bars 18 as at 36 and is extended downwardly and trained. about a pulley wheel 37 on the harrow body, being thence extended up-V wardly and trained about a pulley wheel 38 V on the bar 18 near the point of connection 36 and the chain 31 is finally extended to the locking body and trained about another one ofthe drums 34: therein. This locking body is mounted on the intermediate upper longitudinally disposed bar 18 of the frame while the top 10 thereof is provided at points opposite the opposed drums 3a with inwardly extending slots 41 in which the links of the chains may be anchored. It is apparent that there are two sets of chains 30 and 31 the other set being of similar construction and connected in a similar manner to the other sideof the harrow while handles 41-2 are connected to the terminals of the chains 30. and 31 ina position in proximity to the drivers seat 43 so that the driver may at any time grasp the handles so as to pull the chains and consequently raise the harrow body 19 upwardly from the ground while the chains may be manipulated so that the links thereof may be locked in the slots ll of the locking and retaining body 35. 1 .7

A clevis 4:4: is conneoted to the draw bar 23 and is adapted to receive a draft device of conventional form. I

It is believed in view of the foregoing description that a further detailed description of the operation of the device is entirely unnecessary. Likewise it is believedthat the advantages of the invention will be readily apparent. Y 7
